RAC60-12SB Equivalent & Substitute Parts

Part Overview

The RAC60-12SB is an enclosed AC/DC converter manufactured by Recom Power, delivering 60W of power with a single 12V output at 5A maximum current. This unit is designed for ITE (Commercial) applications and features short-circuit protection (SCP) with input voltage range of 85–265 VAC. The RAC60-12SB is classified as obsolete, necessitating identification of active equivalent and substitute parts for ongoing procurement and system integration.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RAC60-12SB are identified based on the following critical parameters:

Electrical Compatibility:

• Single output configuration at 12V
• 5A maximum output current
• 60W power rating
• Input voltage range compatibility (minimum 85 VAC support required)

Mechanical Compatibility:

• Through-hole mounting type
• DIP module package format
• Physical dimensions suitable for equivalent form factor applications

Regulatory & Compliance:

• RoHS3 compliance
• International safety certifications (CE, cULus, or equivalent)
• REACH unaffected status

The two substitute parts identified—RACM60-12SK/OF/PCB-T and PSK-60D-12—meet these core electrical and mechanical requirements while offering active product status and enhanced operational specifications.

Parameter Comparison

Engineering Selection Recommendations

RACM60-12SK/OF/PCB-T (Recom Power)

This substitute is a direct electrical equivalent with identical power, voltage, and current specifications. It is manufactured by the same supplier as the main part, ensuring design continuity. The RACM60-12SK/OF/PCB-T offers an extended operating temperature range (–40°C to 85°C versus –40°C to 70°C) and improved efficiency (90% versus 86%). It supports both AC and DC input voltages, providing greater input flexibility. The open-frame construction differs from the enclosed design of the RAC60-12SB; this requires verification of thermal management and EMI shielding requirements in the target application. Active product status ensures long-term availability and supply chain stability.

PSK-60D-12 (CUI Inc.)

This substitute meets all core electrical requirements with identical 60W, 12V, 5A specifications. The PSK-60D-12 is an enclosed unit, matching the form factor of the RAC60-12SB. It delivers superior efficiency (91%) and extended temperature range (–40°C to 85°C). The input voltage range differs significantly: 85–100 VAC and 305–430 VDC. This restricted AC input range (85–100 VAC versus 85–265 VAC) limits applicability to systems with stable AC mains voltage. The load regulation specification (±1.5%) is slightly relaxed compared to the main part (±1%). Active product status and CE/UKCA certifications support procurement continuity.

Selection Criteria:

• For applications requiring the full 85–265 VAC input range with AC-only supply: RACM60-12SK/OF/PCB-T is the preferred substitute, with thermal design review required for open-frame operation.
• For applications with stable AC mains voltage (85–100 VAC range) or DC input capability: PSK-60D-12 provides enclosed construction matching the original design.
• Both substitutes are active products with current manufacturing status and full RoHS3 compliance.

Frequently Asked Questions (FAQ)

Q: Can the RACM60-12SK/OF/PCB-T directly replace the RAC60-12SB in all applications?

A: Electrical substitution is valid for applications where the output specifications (12V, 5A, 60W) and input voltage range (80–264 VAC minimum) are compatible. The open-frame construction of the RACM60-12SK/OF/PCB-T differs from the enclosed RAC60-12SB. Applications requiring EMI shielding or specific thermal management must be evaluated for the open-frame design. The extended temperature range (–40°C to 85°C) provides operational advantage over the original part.

Q: What is the primary limitation of the PSK-60D-12 as a substitute?

A: The PSK-60D-12 input voltage range is restricted to 85–100 VAC for AC supply, compared to the RAC60-12SB range of 85–265 VAC. This substitute is suitable only for applications with stable AC mains voltage within the 85–100 VAC window. The enclosed construction and improved efficiency (91%) align with the original design intent.

Q: Are there differences in package dimensions between these parts?

A: Yes. The RAC60-12SB measures 4.29" L × 2.30" W × 1.20" H (109.0mm × 58.5mm × 30.5mm). The RACM60-12SK/OF/PCB-T measures 3.09" L × 2.09" W × 1.39" H (78.4mm × 53.0mm × 35.4mm). The PSK-60D-12 measures 2.76" L × 1.89" W × 1.06" H (70.0mm × 48.0mm × 27.0mm). PCB layout and mounting hole spacing must be verified for mechanical compatibility in the target application.

Q: Do all substitute parts maintain the same regulatory certifications?

A: All three parts hold CE certification and RoHS3 compliance. The RAC60-12SB carries cULus approval. The RACM60-12SK/OF/PCB-T holds CB and cURus certifications. The PSK-60D-12 holds CE and UKCA certifications. Application-specific regulatory requirements must be confirmed before final selection.

Q: What is the difference between line regulation and load regulation specifications?

A: Line regulation (±1% for RAC60-12SB and PSK-60D-12) specifies output voltage stability across the input voltage range. Load regulation (±1% for RAC60-12SB, ±1.5% for PSK-60D-12) specifies output voltage stability across the output current range (0–5A). The PSK-60D-12 exhibits slightly relaxed load regulation, which may affect applications requiring tight output voltage tolerance.

Q: Why is the RAC60-12SB classified as obsolete?

A: Obsolete status indicates the manufacturer has discontinued production. The RACM60-12SK/OF/PCB-T and PSK-60D-12 are active products with current manufacturing support, ensuring long-term component availability and supply chain reliability for new designs and system maintenance.
